Concept of Memory Segments In assembly language, memory segments are logical divisions of system memory, with each segment designated for specific types of data storage. This segmentation model enhances the clarity and security of program organization. Basic Types of Memory Segments 1. Code Segment Stores the instruction code of the program. ; Using section keyword … Read more
📌 Assembly Language Syntax Structure Assembly language is a “machine-oriented” low-level language that corresponds directly to machine instructions. Different CPU architectures (such as x86, ARM, RISC-V) have different assembly syntax, but the core structure is generally similar. An assembly source program typically consists of “pseudo-instructions, data definitions, and instruction statements”. 1️⃣ Basic Structure of an … Read more

0x00 This chapter is dedicated to daily learning and note sharing to help everyone learn assembly language. Why learn assembly language? Because in red-blue confrontations, our tools are often detected and eliminated due to the presence of AV/EDR. Therefore, we need to counter AV, which involves evasion techniques. To learn evasion techniques, we must start … Read more
